Vendor or Partner id for external catalog in ME_CATALOG_INTERFACE_CUST for ME21N

Hi All,

I'm using external catalogs from ME21N and I'm trying to implement a custom logic when returning from it.

For that logic I need to know the vendor (partner) id from the external catalog in method IF_EX_CATALOG_CUST~MAP_CATALOG_VALUES from badi ME_CATALOG_INTERFACE_CUST.

For internal catalogs I can find the vendor id in field ct_oci_item-vendor, but for external catalogs that field is empty.

Do you know how can I get the partner id in that method?

Thanks in advance!
